Product Advantages and Features
Variable displacement axial piston pump, swashplate design for hydrostatic transmission in closed circuits
Infinitely variable flow proportional to drive speed and displacement.
Flow increases with swashplate swivel angle from 0 to its maximum.
Flow direction changes smoothly when the swashplate moving through the neutral position.
Equipped with cartridge-type high-pressure relief valves to protect the pump and motor from overloading
